Fiber Optics Communication Systems

Module Overview

A comprehensive module on optical communication systems aligned with the SPPU Fiber Optics Communication course. Covers physics of light transmission, fiber types, system components, and modern WDM technologies.

Topics Covered

• Principles of total internal reflection and numerical aperture
• Fiber types: single-mode vs multi-mode, step-index vs graded-index
• Optical sources: LEDs and laser diodes
• Photodetectors: PIN diodes and avalanche photodiodes
• Splicing techniques and connector types (FC, SC, ST, LC)
• WDM and DWDM systems
• OTDR testing and loss measurement

Learning Outcomes

Students will be able to analyse optical link budgets, identify fiber types for given applications, and interpret OTDR traces to locate faults.
